Using Map Kit

Using Map Kit

I just bought and watched the MapKit tutorial, but I’m still having trouble getting the hang of MapKit. I’m trying to do something very simple. I want the app to center in on my current location and show a small region around my location. My code compiles fine, but does a force close when I try to run it.

What am I missing?

The logic behind my code is as follows:
Create a region ojbect and 2D coordinate object. Set the coordinate object to be the user’s current location. Set the region center to be the coordinates of the user’s current location. Set an arbitrary span for testing purposes. Set the region to the view.
